DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0021] like Figure 1-Figure 5 As shown, this embodiment provides an explosion-proof self-opening folding umbrella, including an umbrella middle rod 1, an umbrella frame and a stabilizing component.

[0022] The umbrella frame includes six groups of ribs 2 and a connecting ring 23. The six groups of ribs 2 are arranged in a ring-shaped interval along the axis of the umbrella rod 1. The ribs 2 include a first rod body 21 and a second rod body 22. One end of a plurality of first rod bodies 21 is rotatably connected to the upper end of the umbrella rod 1. Specifically, a ring body is formed at the upper end of the umbrella rod 1, and the first rod body 21 is hinged to the ring body. The first rod body 21 has a first through hole and a second through hole. The connecting ring 23 is sleeved on the umbrella rod 1 and slides up and down. One end of the second rod body 22 is hinged to the middle section of the first rod body 21, and the other end of the second rod body 22 is hinged to the connecting ring 23. The peripheral surface of the connecting ring 23 has a bayonet 231.

[0023] The stabilizing component is used to stabilize the wind resistance between adjacent first rod bodies 21. Specifically, the stabilizing component includes five connecting ropes 3, which are connected between adjacent first rod bodies 21. The connecting ropes 3 are connected to the outer side of two first rod bodies 21. The connecting ropes 3 are straightened when the folding umbrella is opened. The two ends of the connecting ropes 3 respectively pass through the first through hole of one first rod body 21 and the second through hole of the other first rod body 21. Nodules 31 are formed at both ends of the connecting ropes 3. The nodules 31 are clamped at the opening of the first through hole and the opening of the second through hole. The connecting ropes 3 are made of stainless steel wire.

[0024] If the umbrella surface is affected by strong wind, the first rod body 21 cannot be flipped upward due to the existence of the connecting rope 3. This is because the first ribs 2 of the umbrella are arranged in a cone shape. When the umbrella is opened, the distance between the two ends of the connecting rope 3 is the farthest. The umbrella surface needs to be flipped after multiple first rod bodies 21 are located in the same horizontal plane. When multiple first rod bodies 21 are located in the same horizontal plane, the distance between the same points of two first rod bodies 21 is the farthest. The length of the connecting rope 3 in this solution is less than the above distance, so when affected by wind, an opposite pulling force will be generated to stabilize the first rod body 21.

[0025] Preferably, the number of connecting ropes 3 between adjacent first rods 21 can be set according to the size of the umbrella, and should not exceed 5 at most.

[0026] The umbrella rod 1 is hollow, and has a holding portion 11 at the bottom of the umbrella rod 1. There is a clamping hole at the bottom of the umbrella rod 1, and a clamping column 13 is arranged at the clamping hole. The clamping column 13 and the clamping column 13 are adapted to the bayonet 231. The holding portion 11 has a first chamber, and the side wall of the first chamber has a through hole. A pressing column 12 is arranged at the through hole. The inward end surface of the pressing column 12 has a through groove. The inner side wall of the umbrella rod 1 has a guide column 121, and the guide column 121 is adapted to the through groove. A spring 122 is sleeved on the circumferential surface of the guide column 121, and a connecting rod 123 is provided between the clamping column 13 and the pressing column 12 located on the inner side of the umbrella rod 1.

[0027] A wire entry port is provided at the upper end of the umbrella rod 1, and a slider 14 is provided inside the umbrella rod 1. A compression spring 15 is arranged between the slider 14 and the upper end surface of the inner cavity of the umbrella rod 1. The two ends of the compression spring 15 are respectively fixedly connected to the slider 14 and the upper end surface of the inner cavity of the middle rod. A connecting wire 16 is arranged between the connecting ring 23 and the slider 14. The connecting wire 16 is made of stainless steel wire. One end of the connecting wire 16 is fixedly connected to the connecting ring 23, and the other end of the connecting wire 16 is fixedly connected to the slider 14.

[0028] Working principle: when the folding umbrella is in the retracted state, the operator holds the handle 11 and presses the pressing column 12, and the pressing column 12 retracts back, driving the clamping column 13 to retract the inside of the umbrella rod 1, and the clamping column 13 and the buckle on the connecting ring 23 are disengaged, and the spring 122 located in the umbrella rod 1 begins to pop out. Under the action of the spring 122, the slider 14 located inside the umbrella rod 1 moves toward the lower end of the umbrella rod 1, and the connecting rope 3 is pulled, so that the connecting ring 23 moves upward until the umbrella rib 2 is unfolded, and the connecting rope 3 is in a straight state at this time. When the umbrella rib 2 is in the unfolded state, the spring 122 in the umbrella rod 1 is still in a compressed state, but the compression amount becomes smaller. Therefore, the setting can ensure that the connecting ring 23 can be pulled all the time, so that the umbrella rib 2 will not shrink under the action of its own weight.

[0029] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
